Conditions studied: Effectiveness of Charcoal-infused Versus Nylon Bristle Toothbrushes on Plaque Removal and Oral Bacterial Reduction in Children

In brief

This study will compare two types of toothbrushes in children: a charcoal-infused bristle toothbrush and a regular nylon bristle toothbrush. We want to see which toothbrush is better at removing plaque and reducing bacteria in the mouth. Children will be randomly assigned to use one of the toothbrushes. We will measure the levels of bacteria in small samples of fluid taken from the gums to see if one toothbrush reduces harmful bacteria more than the other.
